I like how you can use both moderated and unmoderated usability testing. And I remember when I first started, I didn't know what to do first. But they guided what to do and how to conduct a usability test. Review collected by and hosted on G2.com.
The downside of UX testing is that you have to analyze the data you collected from UX testing usability testing separately. It would have been much better if I could have done it within site itself. Review collected by and hosted on G2.com.
